Step 4: Run the sample

The first time you run the sample, it will prompt you to authorize access:

The sample will attempt to open a new window or tab in your default
browser. If this fails, copy the URL from the console and manually open it in
your browser.

If you are not already logged into your Google account, you will be
prompted to log in. If you are logged into multiple Google accounts, you will
be asked to select one account to use for the authorization.

Click the Accept button.

The sample will proceed automatically, and you may close the window/tab.

This app isn't verified.

The OAuth consent screen that is presented to the user may show the warning
"This app isn't verified" if it is requesting scopes that provide access to
sensitive user data. These applications must eventually go through the
verification process to
remove that warning and other limitations. During the development phase you can
continue past this warning by clicking
Advanced > Go to {Project Name} (unsafe).
